7 Claims. (01. 240-81) My invention relates, generally, to lighting uni nd, or pa t cularly, to. lig i un adapted to provide a Source of ordinary ill unination or visible lighthcombined witha source of ultra-violet light.

The object of my invention generally stated is to provide a dual purpose lighting unit which shall be simple and economical to manufacture, and which may be readilyusedior illuminating and therapeutic purposes. 7

A, morespecificrobject of my invention is to providea floor, table or desk lighting unit wherein. provision :is made'for supporting a source of ultranviolet light insuch manner that it may be utilized to the greatest'advantageand with the utmost ease: on the part of the user.

,Anotherobject; ofemy invention is to provide a standardfor a'fioonndesk ortableulamp having a harp section: or element which maybe utilized for supporting a source, of ultraviolet light in the most advantageous manner. i

'.A further object oimyinvention is to provide, in a lighting unit' having a" source :of visible light and a source'ofultra=violet"light, for controlling the. ultraevioletsourceby meansof a voltage ree ducertlocated in the base of the unit.

; 'Still another; objecti'oftmy; invention is to pro-. vide a lightingmunit wherein provision is made for obtaining both direct and indirect illumination and for also iobtaininglultra-violet light rays in the most effective Ianddes'irable manner.

For a more complete understanding of-the natureand objects of my-invention, reference may nowbe had to the d'rawingin which;

,Figure 1.155311 ,elevationatiview of a floor lamp embodying zthe principal features i of my inventiony 1- Fig. 2 is an enlarged detailiviewi of the reflector and mounting for the reflector for theultra-violet lighting unit shown in Fig; 1

Fig.1 3 istamodificationoi the unit illustrated in Eigily v l Eigt'eiis' anienlarged detail view of a modified forniofi reflector-and mounting therefor; and Figsgfi, 6, land- 8 are: diagrammatic views of the connections whichmay be used for energizing and controlling the 'ilightsources employed in the units illustrated iinfiigst 1 and 3.

Referring now toithedrawing, there is illus trated in Fig. 1 a lighting unit commonly known as-la floorlampxcomprisins, generally, an upright member orz'standardj L0 provided at its lower end with abasel l, andat its upper end with a suitable socket liiwhich'may :b utilized to hold a :lightffsource such, :for example, as an ordinary incandescent lamp [3 to provide visible illumina tion. In these respects the'un'it illustrateddoes not differ fundamentally from other well known units of the same general kind and it is to be understood that the novel features of the invention which are to be described in, detail herein after may be embodied in any kind of aunit regardless of its structural and ornamentalchar acteristics.

I have discovered that an ultra-violet light 19 source may be utilized to great advantage by suitably combining it with a lighting unit of] the en type h h Whe h r it b ah rd ar floor lamp, reading lamp, table "lamp, bridge lamp, therapeutic lamp or otherwiS e; in such manner that the ultra-violet source may be uti' 15 l d b an us n t i in unit 'or y anyone in the near vicinity thereof.

In order to accomplish this purpose, the up;- right member or standard is Provided with a suit- 20 able intermediate section or member i4 for onvenien a be ed a h whi h may e utilized as a mounting or support for the ultravioi i light source 5 h h may take the ioihi of a lamp, as shown i 25 In this particular instance, the harp H} is provided with a suitable socket l5 whichjis adapted to support the ultra-violet lamp IS in adown- Ward iti n, as she hlt l b r adi d stqe i of course, hat t ii h'ai ie lamp !5 ma b moun n an esire pos i alt ugh it ho d e re erab y so mounted and bee iohea s o p ovi e a symmeh'ieai =il-191i d i n V A il u tra d t h 4 c rcu ar in shape as b t y ot er rabl sha e or term mayb s d, su h for e e a o al, e an ular he?? agonal or the like, or it may be openon one side with a S gle bow mbe r wh t v r sha e i may be, cated in a y de d es t eh with re- 40 spect to the lamp IS. The harp maybe formed s a int ra part of the standa d or as e Separate element.

I i also o be d r oo that the position o t e h r w r s e h eba e i i, may bee desired and to best suit the use for which it is intended and to comply with the tastes of the designer and purchaser.

In order to provide for controlling to some extent the direction of the ultra-violetraysfrom ,59 t e lamp '5 t ere is r vi e ui b e re le tor which ma e a i s ab authorise ih ehr suitable manner adjacent to the lamp l5 In this em iment e he e ion t e e t r s .19- ported by means of a U-shaped member matsource of ultra-violet light visibly mounted within the harp section, a reflector, and means secured to the standard for supporting the reflector adjacent the ultra-violet light source for directing the rays therefrom.

4. A lighting unit comprising, in combination, a source of visible light, a standard provided with a socket at the top thereof 'for supporting the source of visible light and a base for supporting the standard, a source of ultra-violet light, a harp device of circular shape interposed intermediate the socket at the top of the standard and the base and constituting a supporting portion o the standard for visibly supporting the source of ultravioletlight below the source of visible light and at a different height from the base than the source of visible light, and reflector means secured directly to the harpdevice for directing the ultraviolet radiations. 5. A lighting unit comprising, in combination, a source of visible light, a standard provided with a supporting base and a socket at the top thereof for supporting the source of visible light, said standard being divided into two sections, a source of ultra-violet light, means joining thetwo sections of the standard together for visibly supporting the ultra-violet light source intermediate ,the base and the source of visible light, said means constituting a supporting section of the standard, and a reflector adjustably mounted upon said means for directing the ultra-violet radiations.

6. A lighting unit, in combination, a source of visible light, a standard provided with a base and a socket at the top thereof for supporting the source of visible light, a source of ultra-violet light, said standard being provided with a sup porting harp section intermediate the base and the socket, means for visibly supporting the source of ultra-violet light within the harp section below the source of visible light and at a different height from the base than the source of visible light, and a reflector supported by the harp section for directing the radiations from the ultra-violet light source.

7. A lighting unit comprising, in combination, a plurality of incandescent lamps, a standard provided with sockets at the top thereof for supporting said lamps and a base, a reflector shade supported by said standard adapted to direct the rays from some of said lamps upwardly and the rays of others downwardly to provide indirect and direct illumination, said standard being provided with a supporting harp section intermediate the top and base, an ultra-violet lamp visibly mounted in said harp section, and adjustable reflector means mounted on the standard for directing radiations from the ultra-violet lamp.
